final-storage data
Data that resides in final-data memory.
Flash
A type of memory media that does not require battery backup. Flash memory, however,
has a lifetime based on the number of writes to it. The more frequently data is written,
the shorter the life expectancy.
FLOAT
Four-byte floating-point data type. Default data logger data type for Public or Dim vari-
ables. Same format as IEEE4.
FP2
Two-byte floating-point data type. Default data logger data type for stored data. While
IEEE4 four-byte floating point is used for variables and internal calculations, FP2 is
adequate for most stored data. FP2 provides three or four significant digits of resolution,
and requires half the memory as IEEE4.
frequency domain
Frequency domain describes data graphed on an X-Y plot with frequency as the X axis.
VSPECT vibrating wire data is in the frequency domain.
frequency response
Sample rate is how often an instrument reports a result at its output; frequency response
is how well an instrument responds to fast fluctuations on its input. By way of example,
sampling a large gage thermocouple at 1 kHz will give a high sample rate but does not
ensure the measurement has a high frequency response. A fine-wire thermocouple,
which changes output quickly with changes in temperature, is more likely to have a high
frequency response.
FTP
File Transfer Protocol. A TCP/IP application protocol.
